Great app! – Slow Fast Slow - Control the Speed of Your Videos Review

The other apps I tried were all bad and kept crashing, or had way too little limited amount of video. But this, this is the best app in all of them. The only thing I wish this should have is backwards audio. If it is possible, I cannot make the backwards audio play. Otherwise, this is the best app. There is one bug though. The videos appear black on the "other videos" section. Please fix.
